Specification of Letters-Patent. Patented Ang 19, 191 9 A Application filed November 13,1918. Serial No.'262,371.

the same is to produce a fluid power unit especially applicable for usewith wind or water, and wherein the impelling fluid actuates the rotor both by impact and by pressure during a full half of the revolution thereof. 1 I

A further feature of the invention is that of the ieatheringblades orp'addles, and a yet further feature is the means for regulating the inlet of the motive; fluid.

Details, are set forth in the following specification and claims, and attention is invited to the drawings, wherein Figure 1 is a plan view of thisstru'cture with the top omitted, showing-the rotor as mounted on a substantially circular platform.

Fig. 2 is a side elevation of this invention showing the .rotor ,asalmost completely housed within a casing, and illustrating especially the track-or cam on which the roller at the outer corner of each paddle or blade travels,

Fig. 3 is 'a perspective view of yet another form of thisinvention with-the trackand rotor omitted, and in which the .walls of and partition within the rotor end-of the structure are mounted upon a comparatively Fig. 4: is a perspective detail of thes jrotor I andone paddle or wing.

Considerable latitude is possible with respect to the housing or casing of thls machine, the character, velocity,- and volume of the motive fluid necessitating. modifications therein as will be clear. For, instance the 'bottom=-or platform 1 of ;th e housing shown in Fig. 1 is substantially circular, and the top whichlis there omitted would be the same; the housing or casing in Fig. 2 isbox shaped. at the frontand includes a bottom or "platferm '3 which extends be 'neath the rotor, and a top 4. which overlies the rotor to the point 5, the rotor itself here having a top 6; and the bottom or platform 7 in Fig.3 not only underlies the rotor but extends forward of the same in fanshape to permit adjustment of the doors or gates as descrlbed below, the top in this shape. In any event, however, the fixed walls arev two in number, respectively indicated at8 and 9, and each is struck on a curve and extends around the rotor chamber 'casebeing preferably about of the same,

for a little more than ninetydegrees, these walls being set about opposite each other. Betweenthe inner end oftheiront wall 8 and the front end of the rear Wall 9 is an inlet opening .10 disclosed clearly in Fig. 3 andhdesignated by the arrow 11 in F1g. 1. Between the rear end of the front waneand the inner end of the rear wall 9 is'an outlet opening designatedlQ in Fig. 3, indicated by the arrow/"13 in Fig. l, and hidden by the paddle at the right of Fig.

2 The numeral 14 designatesa rigid radial partition extending along one side of the outlet, ando'verwhich partition the several paddles must pass as described below.

'Hingedat 15 to "the front'end ofthe fixed,

walls. are gates or doors 16 and 17 which may be adjusted overthe bottom or "platform, between the' bottorn and top, or even where there is no "bottom and top.: While any form of adjustment is permissible, I J

prefer-to provide these gates or doors with openings or holes 18 in'their upper edges to receive pins1 9 'vv hich will pass. through the top 4: if there vbe atop tothe casing,

or will pass'through corresponding holes in rodsor bars 20whieh areappropriately pivoted as at 91 and22 to some fixed portion of the: device. A. top bar 23 also having holes 9A may connect the-forward ends of the doors or gates, the samepins 19 being 17 to be swung-on their hinges .15 so as to control the flow of fluid into the inlet openemployed or others numbered .29. The .pur-

,pose is. topermitthe gates or doors 16 and ing 10, whether said fluid be air or water,

The fluid entering the casing between the walls sandfe. is appliedfto the rotor. yet to be described and passes. around therein and whatever its direction .of approach.

a d out at the u et op in a r of the easm'gend. at "one side thereof, but

through the bottom 1 at a central pointbetween the walls 8 and 9 as indicated at 31 in Fig. 3, and it may or may not have .a bearing in the top of the casing if the latter has a top. A bearing is indicated in Fig. 2 by the numeral 32, below which the shaft is extended for carrying a driving,

wheel or otherwise performing service. It is obvious, however, that the shaft could risefrom the casing and the driving wheel be applied to its upper end. .Within the casing this shaft carries a plurality of spokes indicated at 33, their outer ends being connected by a ring 34. Over these spokes and rings in Fig. 2 the rotor has a top plate .6, but in other views the rotor has no such top plate. It will need none when thereis no top to the casing, and it needs no bottom plate because the casing always has a bottom. The ring is supported and braced by braces 35, each extending obliquely from the outer end of a spoke to a point on the shaft'30 just above the opening 31 in the platform through which the shaft passes. By preference there are four spokes and four braces. Hingedly hung at 36 on each spoke is a wing or paddle 37, preferably consisting of a frame with suitable, braces across it, and a light fabric sheet stretched within the frame. It is important to note from Fig. 4 that the wing is hung from the spoke in rear of the brace 35 in the direction of rotation which is indicated by the arrow, and therefore the wing when it hangs pendant rests against the brace and cannot be moved forward, although it may be folded backward as indicated in dotted lines. At its lower outer corner the wingcarries a roller preferably in the shape of a ball 38." The spokes and the wing 34 travel over the partition 14, and in order that the several. wings shall pass over the frame when they reach it there is provided a track or ,cam on which the several rollers travel. Thistrack rises at 41 from the point 40 ratherfabru'ptly, to the point 42, whence it extends horizontally at 43, over the partitionl i as seen in Fig. 2, to the point 14: inside the front wall 8, and thence it descends again as at 45 toabout the point 46 in Fig. 1, where it is level with'or perhaps carried upon the bottom of the easing. or platform.- In fact, the track might be omitted through-the right halfv of the rotor portion of the casing as shownin Fig. 1, and the spherical roller ,,38 allowed to travel upon the base or platform 1.,

With this construction of parts, the operation is as follows: The adjustment of the doors or gates 16 and 17 need hardly be amplified. They will be set toward the prevailing direction of the wind if it be wind that is employed as the fluid motive agent,

hinges 15 and 15. The paddle or wing in dicatedat a is just moving past one of said hinges, and some of the fluid catches behind this wing and carries'it'forward to the point 6, the bulk of the fluid carrying the wing 6 forward to thepoint 0 and of course having less and lesseflect upon the second wing as it increases in its effect upon the first wing a. By the'time the wing b has reached the point 0 the wing (Z has reached the point a,

but the power of the motive fluid agent is exerted on two wings constantly and throughout a full half revolution of the rotor. As

any wing passes the point 10 its roller 38 begins to ascend the rise 41 of the track, and the motive fluid is permitted to flow out the outlet openlng While the roller is passing along the horizontal stretch 43 in Fig. 2,

the wingstands horizontal'as there shown and as best illustrated in Fig. 1, and in such position it can easily pass over the partition 14. The latter is useful, for preventing eddies or currents of the outflowing fluid from being carried around with the rotor,

producing the undesirable churning effect so prevalent in machines of this type. Therefore there is no moving motive fluid aflecting the wing which passes over the partition and while it is descending along the fall 150f the track; and just as it becomes again vertical at the point a, it passes from behind the inner end of the front wall 8 and receives another blast of air or water as described above.

The foregoing description and the drawngs have reference to what maybe consideredthe preferred, or approved form of my mvention. It is to be understood that I may make such changes in construction and arrangementand combination of parts, materials, dimensions,,et cetera, as may prove expedient' and fall within the scope of the appended claims. 7

Havingjthusfully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a device of thefclass described, the

combination of a casing comprising abase having a pair of fixed walls thereon, said walls being curved throughout their entire length in thearc of a,circle, one of said gates adjacent their outer ends, a top bar directly mounted upon said gates, whereby the gates will be adjustably held in set positions to direct fluid into the interiorof said casing, and a rotor revolubly mounted within said casing.

2. In a device of the class described, the combination of a casing including a short transversely extending partition, a rotor revolubly mounted within said casing and including an upright shaft having radiating spokes, paddles hingedly mounted upon said spokes and depending therefrom, diagonal braces fitting in the rear of said paddles as the rotor revolves to reinforce the same so that as fluid pressure bears upon the paddles the rotor will revolve, the lower outer edges of said paddles being unobstructed, rollers carried upon the lower outer edges of said paddles, and a track comprising a horizontal portion extendingabove sald partition and downwardly curved end portions, whereby as the rotor revolves, said rollers will strike said track and will ride upwardly to hold the paddles in horizontal position as the same pass above said partition and then allow the paddles to move downwardly to receive the force of fluid pressure entering the casing.

3. In a device of the class described, the combination of a casing comprising a base having a pair of fixed walls thereon, said walls being curved throughout their entire length in the arc of a circle, one of said walls being shorter than the remaining wall, elongated gates hingedly mounted upon the ends of said fixed walls, bars pivotally mounted upon said short fixed wall and being adjustably connected to said gates adjacent their outer ends, a top bar directly mounted upon said gates, whereby the gates will be adjustably held in set positions-to direct fluid into the interior of said casing, and a rotor revolubly mounted within said casing.

In testimony whereof I aflix my signature in presence of two witnesses.
